RE#: how we built the world's fastest regex engine in F#, https://iev.ee/blog/resharp-how-we-built-the-fastest-regex-in-fsharp/.
Excellent blog post!
Very interesting approach with new operations: intersection (&) and complement (~).Implementation: https://github.com/ieviev/resharp-dotnet

My tip of the of the day.
To match a literal dot "." with a regular expression, write
"[.]"
instead of
"\\." or "\\\\." or even "\\\\\\\\.",
depending on context. 😀

How do I use regular expressions to mute specific terms without muting them if they're just part of a word?
So like, in a stupid example:
I want to block "lol" but not "testloltest"

My PhD student was still feeling uncomfortable with #regex, so I searched and found these awesome regex games that can help you improve your regex-fu and help you have some fun during your daily commute:

and this imho is more geared towards beginners:

Just saw someone use "regexpert".
Gonna have to remember that one.

At some point there had to be a competition for who can create the most fked up syntax for regular expressions. And I feel like #vim was probably in the top three. Non-greedy being \{-} is WILD.
(Yes, I'm aware of the history, it's a joke. But also apparently nobody ever thought about standardizing it for developer's sanity)

Things I Learned Today
#TILT #bash #linux
Still working on #regularExpression in bash.re='^~\s~\s~'
if [[ "${lineN}" =~ ${re} ]] ; then bla bla bla...The extra variable declaration is needed; found on web
"While not always necessary, it is advisable to store the regex in a variable first, because Bash has trouble with regex literals containing \." -
Things I Learned Today
#TILT #bash #linuxIt took me while to figure this out and now I remember that I fell in this hole before.
When using #regularExpression like:
if [[ ! ${suffix} =~ .*voScript.txt$ ]] ; then echo "something" ;fi
do NOT quote the regular expression. It is not a string.

Best answer on regexps ever? 🧐 😎
- What is the plural form of regex?
- If you've used more than one of them, you'll know that the plural of "regex" is "regrets." – cjs (Mar 14, 2022 at 23:46)

@tripleo You’re thinking of #Perl’s “taint mode” (stop your teenage giggling), where outside data is untrusted unless it’s the extracted subpattern match in a #RegularExpression.
It’s only enabled under certain conditions. Read about it in the `perlsec` manual page: https://perldoc.perl.org/perlsec#Taint-mode

Just so we're clear: I include #Matrix direct messaging link in format of https://matrix.to/#/@vintprox:envs.net 👌...which #YouTube has no trouble with. The reason I even publish DM link instead of my #MatrixSpace, though, is because YouTube has a meltdown from links containing a second # (number sign, replace @ with it to get into my space).
From technical POV, it's one correct #RegularExpression away for YouTube, as many modern social media and video platforms can handle it and do use normal #regex. But, on the other hand, #MatrixTo service just shouldn't be employing such flawed #URL pattern or provide an alternative one, even if #URI standard allows the former to exist.
So, yeah, there is that - it is hard to gather video viewers in such a place. It's a single thing that I miss from Discord invite links. Matrix ones don't need a vanity and it's sweet - one solution is put it through #URLShortner, but then the entire point is lost.
